Who are we?

BIOLOGY4KIDS launched in 1997 and was originally a part of the Chem4Kids site. Over time, we built a series of introductory chemistry, biology, geography, physics, astronomy and math sites. While the original sites were built for primary school students, we discovered that all sorts of people were coming to the sites.

We are always happy that the sites are able to reach so many people around the world. Science and technology (STEM topics) should be enjoyable to everyone. We have fun making the sites and we hope our visitors have a good time while they are here. If you want to see what chemistry pages are available, visit our site map.


All of the Rader's sites use some plug-ins...
- Adobe Flash
- Apple QTVR
- We're trying to make our new activities in HTML5 so that iOS users can use the materials in the future.
